I To all whom it v of California,

Be it known that I, Josnrrr Bambi Quinta citizen of the United'-States=,-residing at-Fair Oaks in thecounty--o $acrament6, State have invented certain new and useful Improvements in HingeSeat Cutters; and I do *declare the following to be a full, clear, and exact description'of the same, such as will enable others skilled in V a part of this application.

the art to whi h it appertains to make and use the same,-reference being had to the accompanying drawings, and to the characters of reference marked thereon,

This invention relates to improvements for making sockets in doors and door jambs to receive butt hinges the object of the in-,

. which will perform this operation in a much perspective view of a guide.

less time than the hand method now'emloyed.

A still furt er object of the invention-is to produce a simple and inexpensive device.

and yet one which will tive for the purposes signed.

These objects, I accomplish by means of such structure and relative arrangement of parts as will fully appear by'a perusal of the following specification and claims.

In the drawings similar characters of refbe exceedingly efiecfor which it is deerence indicate corresponding parts in the several views.

Figure 1 is a side elevation of the complete machine. Fig. .1 is a fragmentary portion of said machine showing a slotted guide member. Fig. 2-is a side elevation of a cutter for the machine. -Figg2' is a frag? mentary portion of the same. Fig. 3 is a Fi .-4.is a side elevation of a guide means. ig. 5 is a front elevation of a fragmentary portion of a door and door jamb showing the socket as made by my improvedmachine. Fig. 6 is an inside view of a door and-door jamb showingsaid sockets. Fig. 7 is a side elevation oi a supporting bar to be used in connection with my improved machine if desired.

Having thus described my invention what I claim as new and useful and desire to sel cure by Letters Patent is:

1. A. device of the character described comprising a handle member having projectmg arms provided with guide slots. in

said projecting arms, means for operating said saw and independent guide members adapted to be fixed stationary independently of said arms and to fit into said slots as described.

2. A' device of the character described comprising ried by said arms, means for operating said a handle I member, projecting. arms on said-handle member provided with slots on their outer edges,'a rotary saw car-- saw, independent guide members fixed sta- I tionary independently of said projecting arms and adapted to .fit into said slots a supporting bar having'slots adapted to fit over said guides, and springs on said supporting bar adapted to press against said arms as described.
